title: Naringin protects against kainic acid-induced status epilepticus in rats: evidence for an antioxidant, anti-inflammatory and neuroprotective intervention.
abstract: The effect of naringin, a bioflavanoid, with potent antioxidant activity was studied on kainic acid (KA)-induced seizures, cognitive deficit and oxidative stress. Rats were administered KA (10 mg/kg intraperitoneally (i.p.)) and observed for behavioral changes and incidence and latency of convulsions over 4 h. The rats were thereafter sacrificed and oxidative stress parameters like malondialdehyde (MDA) and glutathione (GSH) were estimated in the brain. The level of proinflammatory cytokine, tumor necrosis factor (TNF)-α was also determined in the rat brain. It was observed that pretreatment with naringin (20, 40, 80 mg/kg, i.p.) significantly (p<0.001) increased the latency of seizures as compared to the vehicle treated-KA group. Naringin (40, 80 mg/kg) also significantly prevented the increase in MDA and fall in GSH levels due to KA. In addition, naringin dose-dependently attenuated the KA-induced increase in the TNF-α levels of brain. The pretreatment with naringin also significantly increased retention latency in the passive avoidance task. This shows that naringin reduced the cognitive deficit induced by KA. The results of our study suggest that naringin has therapeutic potential since it suppresses KA-induced seizures, cognitive impairment and oxidative stress in the brain. These neuroprotective effects are a result of its antioxidant and anti-inflammatory activity.
